Title
(ZH) 用于净化含NOx废气的装置
Abstract
(ZH)

一种用于净化含NOx废气流(2)的装置(1),包括一个通道(3),它被含有NH3的反应剂(4)通流,其中通道(3)具有外壳部件(5),它包围通道(3)并且包括用于输入含有NH3的反应剂(4)的进入孔(6)和排出孔(7)。外壳部件(5)可以被含有NOx的废气流(2)绕流,其中在外壳部件(5)上连接一个用于分配含有NH3的反应剂(4)的分配部件(8),由此利用分配部件(8)将含有NH3的反应剂(4)加入到废气流(2)里面并且可以与废气流(2)混合。分配部件(8)具有开孔(9),通过开孔将含有NH3的反应剂(4)作为气相导入到废气流(2)里面,其中含有NH3的反应剂(4)在外壳部件(5)内部蒸发。所述外壳部件(5)包括传递热量的部件(10),由此可以利用废气流(2)加热外壳部件(5)。
